| 摘 要： | 目的：测试服用和未服用β-受体阻断剂的心梗后患者（PMIP）在跑台运动中其功能、生理、临床及自我感觉方面的反应。方法：46名服用β-受体阻断剂的男性PMIP和55名未服用β-受体阻断剂的男性PMIP进行递增负荷运动实验，其间记录每级负荷时的摄氧量（VO2）、心率（HR）、血压和自我用力感觉（RPE），并持续监测12导联心电图（ECG）。结果：服用β-受体阻断荆的患者其安静时和运动中的HR、最大心率百分比（％HRmax）及心率血压乘积（RPP）显著低于未服用β-受体阻断剂的患者（P〈0．01）。运动中，服用β-受体阻断剂的患者有59％能够完成改良布鲁斯跑台方案的第Ⅳ级运动，而在未服用β-受体阻断剂的患者中仅有49％能完成这一负荷。两组在运动中各级别VO2、RPE及ST段下移无显著性差异。结论：由β受体阻断剂所致的HR降低并没有直接地影响到氧利用和代谢机能。 |

| Abstract: | The purpose of this study was to examine the functional,physiological,clinical and perceptual responses during treadmill exercise of post myocardial infarction patients(PMIP) with and without beta-blockade therapy.Forty-six male recent PMIP with beta blockade therapy and 55 male recent PMIP without beta blockade therapy performed a graded exercise test.During which,the oxygen uptake(O_2),heart rate(HR),blood pressure and ratings of perceived exertion (RPE) were recorded,and a 12 lead electrocardiogram(ECG) was monitored continuously.The result showed that patients using beta-blockade had a significantly lower(P<0.01) HR,percentage of maximum heart rate(%HRmax) and rate-pressure product(RPP) both at rest and during exercise.During exercise 59% of patients using beta-blockade completed stage IV of the modified Bruce treadmill protocol,whereas in the non-blockade group,only 49% of the patients achieved this stage.There was a non-significant difference between the two groups in terms of O_2,RPE and ST segment depression at any stage during exercise test.Conclusion:The reduction in HR as a result of beta blockade does not impact directly on all other aspects of metabolism and oxygen utilization. |
